when I use actuactor in spring cloud, need to set some configuration like this:

info:
  app:
  name: '@project.artifactId@'
  java:
    source: '@java.version@'

but in this way,when i enter "localhost:8200/info",it show it's literal meaning liken this:

{
"app": {
"name": "@project.artifactId@",
"java": {
"source": "@java.version@"
}
}
}

in actuator documentation,it should shows like this:

{
"app": {
"name": "microservice",
"java": {
"source": "1.8.0_92"
}
}
}

how did I resolve this problem?

This is really a yaml usage question. Try with single quotes around the value like secret: '@t3mokz%OQwkM%fOg#P2'

This is not related to Spring Cloud Config. If you have an actuator question than best to ask a question on StackOverflow or the Spring Boot Gitter channel.

it is related to your scan config:
1.check your pom.xml file and make sure the tag <build> is exsit.
2.then point the resource directory to your yml/xml file
